Sidney Crosby brought the 2,000-plus crowd to its feet with a goal late in the period. He took a pass, split two defensemen with extreme acceleration and fired a shot on net. Andrew Penner made the first save, but Crosby banged home the rebound.

Armstrong roofed a penalty shot to knot the game at 3-all before intermission.

Christensen and Armstrong converted penalty shots in the second period. Armstrong slid home an empty-net goal to seal the win.
